<br><br><br>Purely from a technical standpoint, it makes sense to use XMPP. He does describe dual-headed clients that support both xmpp and sip .. somewhat analogous to the pulver pro beta client.<br><br>Here's an old article describing some of the issues:
<br><br><br><a href="http://www.infoworld.com/article/03/05/23/21FExmpp_1.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.infoworld.com/article/03/05/23/21FExmpp_1.html</a><br>and the person involved is now at cisco:

http://www.jabber.com/index.cgi?CONTENT_ID=55&VMX_TRACKED=YES</a><br>and ... <a href="http://www.jabber.org/protocol/xmpp-simple.shtml" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://www.jabber.org/protocol/xmpp-simple.shtml</a><br>and some other comparisons from a commercial standpoint: <a href="http://www.jabber.com/index.cgi?CONTENT_ID=619&VMX_TRACKED=YES" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://www.jabber.com/index.cgi?CONTENT_ID=619&VMX_TRACKED=YES<br></a><br>Note that there are a ton of RFC's describing extensions to sip to make it do what xmpp already does.<br><br>I think the one item that SIP/SIMPLE has going for it in one aspect is that of point-to-point communications
<br><br><br>with no intermediary server requirement for transport once sessions are implemented (excluding gateways etc obviously)...<br>The perceived need for telco's to provide that type of infrastructure appears to be somewhat relevent.
